    HELLO PEOPLE ME AND DAVID HAVE DECIDED TO BUILD A JET CAR THE DESIGN IS BASED AROUND A LARGE TURBO CHARGER, IT WILL NOT RUN AT POD IT WILL NOT DO 1/4 OF A MILE IN 7 SECONDS. BUT IT SHOULD MOVE THE WEIGHT OF ONE MAN AND A CART FORWARDS 1MPH AND I WILL BE HAPPY . THE DESIGN IS VERY SIMPLE AND THERE ARE LOADS OF WEBSITE OUT THERE, I PUT A POST UP IN SUPORTING THREADS SO IF ANY ONE DOES FIND A WEB SITE POST IT IN THERE SO ANYONE CAN BUILD ONE IF THEY WANT. IM GOING TO POST UP PICS OF THE BUILD AS IT GETS BUILT. IF ANYTHING IT WILL WARM US ALL UP AT THE WEDNESDAY MEET AND SHOULD BE VERY FUNNY.


    FIRST I STARTED TO BUILD A COMBUSTOR, I TOOK A PIECE OF STEEL 5 INCH PIPE I CHECKED FOR CRACKS AND DAMAGE BUT ALL GOOD.

    I THEN TOOK A SHEET OF STEEL AND MARKED AND CUT TWO CIRCLES ONE BIG AND I LITTLE . THE LITTLE ONE I CUT OUT THE CENTER SO I HAD A 20MM THICK POLO, WE DRILLED MARKED AND DRILLED A HOLE IN THE POLO ALSO IN THE BIG CIRCLE . WE BOLTED THE LITTLE ONE TO THE BIG ONE AND WELDED NUTS TO THE SMALL POLO AS I WOULD NOT BE ABLE TO TIGHTEN THEM ONCE THEY ARE IN PLACE. I WELDED THE SMALL POLO TO THE END OF THE POLE. DAVID CAME UP WITH A GOOD IDEA OF USING AN ELECTRICAL SANDER TO FLATEN OFF OUR TWO MATEING SURFACES.
    WHICH WORKED A TREAT.
    WE USED A RUBBER GLOVE AND A BUCKET OF WATER TO PRESSURE TEST THE SYSTEM AND THERE WHERE NO LEAKES.

    STILL MISSING A FEW PARTS IF ANY ONE CAN HELP THE GIANT BM MEET HEATER FUND OR KNOW WHERE I CAN GET THEM LET ME KNOW
    ALSO IF ANYONE WANT TO HELP BUILD A TEST IT PM ME YOUR ALL WELCOME TO COME AND GET YOUR HANDS DIRTY

    1 X GIANT TURBO OFF BUS OR LORRY PETROL OR DESIEL
    1X OIL COOLER
    1X OIL CATCH TANK
    1X OIL FILTER HEAD THE PART YOU FILTER SREWS INTO
    1X PROPANE BOTTLE + HOSE
    1X 2INCH EXHAUST PIPE ABOUT A 2 FOOT LONG
    3X SOME OLD GAGES OIL PRESSURE BOOST TEMP
    1X CHASSIE OLD KID GO KART

    THIS ENGINE SHOULD MAKE 65LB OF TRUST 30MPH

    why you thinking of offering your in the name of scientific research?

    as big as you can get ideally, bigger the turbo, greater the power!!

    yeh the bigger the better would like to find a truck one maybe 13inch across would be nice but might have to go with a t3 t4 as there are loads about and there cheap.

    i did have a look at the pulse jet but there a bit simple really and you have to build really big ones to get any real trust . with the turbo one you blow a leaf blower into the induction side this starts eveything spining once the gas has started to combust its force leaving the combustor will spin the exhaust side of the turbo up.As the exhaust side off the turbo is connected to the induction side. you sould be able to remove the leaf blower and it will run all on its own.Then its just a case of pumping more propane in and spining the turbo faster + faster to much propane and the flame will melt the ehaust turbines not enough and it will stall.

    havnt got a turbo yet need to find a big one really big

    yea i get the basic idea of what your doing , you really need a scannia turbo

    big rig size or bigger.... worth trying to find a big scrapheap or even e-gay might have something like that!

    if your having any issues with fixtures or need components made up mate i have access to full workshop facilities , engineer by trade

    just give me a shout!
